I just got off the phone with the product managers for the SpyderTV and the SpyderPRO. Here is the latest official scoop:
1) The sensors in the TV and PRO are different!! It seems that the beta test hardware for the SpyderTV (STV) was just the current Spyder2 hardware with the new shell on it. According to them, the shipping SpyderTV will have even better hardware. I was not unhappy with the current performance. I am now expecting to be ecstatic with the new stuff - it will arrive this weekend, barring FedEx barfing on the delivery.
2) The current upgrade path is the standard "25% loyalty discount" when bought direct. There will be a software upgrade path, but only once the Spyder2PRO package starts shipping with the new sensor (basically, wait until the v2.0 release). Pricing has not been determined yet for the software-only upgrade path.
3) This now makes my default recommendation be for folks to buy the SpyderTV if you are looking to buy today, and then upgrade the software later if you want to add the ability to do profiling, printers or cameras.
Folks, I think this should clarify all of the outstanding questions, except the biggest one: just how good is the new "secret sauce" in the STV?
Also, yes, I am a bit miffed that I wasn't told a) when the beta had closed (a "thank you, we're done" e-mail would have sufficed), or b) that the hardware had changed. I apologize to everyone to whom I have given incorrect information. I now need to update the other four+ threads that deal with the Spyder on the forum.
